RAIL-FASTENING.

Specification of Letters Patent.

Patented Feb. 10, 1914.

Application illecl May 8, 1913. Serial No. 766,280.

To all 107mm it may concern Be it known that I, Inion Fanqmi, of 52- Ruede Louviers, St.-Germain-en-La ye, (Scine-et-Oise,) France, haveinvented au Improvement in Rail-Fastcuings, of which the following is afull, clear, and exact dcscri )tion.

Tire rails of railway tracks are generally secured to the woodensleepers by screw spikes, the resistance of which to the pulling ortearing stress decreases rapidly under the action of the strainsdetermined by the pussage of trains traveling at a high speed and maysometimes become insuilicieut for 1asuring the holding of the rail onits hearings or supports; thenceforth the sec irity of the track 15compromised and accidents may happen. I

1e present invention overcomes this scr1- ous inconvenience by insuringthe fixation of the rail by means of a device offering a resistance tothe pulling stress always equal to the breaking strain oi. the metal ofwhich it is constituted, allowing, without any screw threading, a muchmore secure clamp ng than that of the screw spike and opposm any sinkingof the rail on its supports, al these conditions being necessary forinsuring the fixation of the rails on the wooden slee ers made of anyspecies of wood.

'1 liS invention will be described hereafter with reference to theaccompanying drawing. in which:

As illustrated in Figs. lto 17 at the drawings, the present device.adapted to secure the rails of railway tracks on the wooden slee )GI'S,comprises: 1, a socket A; 2 a wedge B; d, a cramp C; 4, a key D.

The socket A. which has a cylindrical shape, is hollow for a part. ofits height and is provided with a rib or flange a. at its lower part. Atits upper part said socket is provided with a shoulder b and aprojection 0. "Within the socket A is formed an eccentric cylindricalrecess (1 with two diametrically opposed slots 0. The under side of saidrecess and of the two slots constitutes a shoulder f in the socket. Thefoot of the rail E lies on the shoulder 22 of the socket and against thevertical part. 7), while said socket is fitted in the sleeper F. Thewedge B presents an inclined part 7 having an oblong central recess h,two diametrically opposed vertical slots '1'. and two side rihsmoreover, a lower cut away part. 7.: allows of avoiding or passing theproieetion 0 oi the socket when fitting up the parts. The cramp Ccomprises a stem 2, an eccentric head on. inclined parallel to the wedgeand a T- shapcd part a. The head m is provided with two diametricallyopposed slots 0.

The socket. A being fitted in the sleeper F, for securing the rail bymeans at the present device the edge of the rail foot, is laid on theshoulder 7) of said socket. thou the cramp O is inserted in the wedge13, the eccentric part of the head m being thus turned toward the noseof the we; go; this being done. the cramp C is fitted into the recess (5of the socket and the cramp and wedge are caused to rotate through aquarter of a revolution, so that the nose of the wedge should he turnedtoward the rail and that the T-member n engages behind the innershoulder f of the socket; the parts being thus fitted togather, the wede B is driven toward the rail, two keys 13 are fitted into thecorrespondin grooves a i e of the members and i re fixation of the railis thus insured. The oblong recess 72. provided in the wedge B allows todrive it toward the rail, w iile the two ribs j between which is engagedthe head at of the cramp prevent the latter from rotatin The projectiono of the socket guides the wedge during the time the latter 1S driventoward the rail.

The keys D prevent the wedge B from moving backward and the cramp C fromrotating. A single key would be sufficient for securing this device.\Vhen said device is to be removed, the parts are disengaged in thereverse order from that indicated above. Similar devices are arran ed atintervals on both sides of the rails. The above device might beconstructed as illustrated in Figs. 18 to 27 of the drawings. Thismodification of the device com rises a cylindrical member A and a wedgeB. The cylindrical member A is provided with a run a, an upper shoulderb, a flange p, with lateral grooves g and q and a head 1'.

The wedge B comprises a nose .9, the lower face of which is inclinedparallel to the foot of the rail, an inclined part 9' and an oblongrecess presenting two different openin s It and h. The cylindricatmemherA being placed into .position in the sleeper F, for securing the rail Eto the sleeper bfy means of this device, the edge of the rail oot islaid on the shoulder b of the member A, then the wedge B is engaged onthe head 1' of said member A andthe wed e B is driven so that inclinedpart 9' of the latter rubs on the inclined groove During thisdisplacement of the wedge, the nose 8 of the latter has clamped the edgeof the foot of the rail against the shoulder b of the member A and thefixation of the rail is thus insured. \Vhen laying down this device,care should be taken to turn the nose 3 of the wedge B on the sideopposite to the direction of runnin of the trains so that the slippingof the rm s, resulting from the reaction, should cause the tightening ofthe wedge.
